z-test problems 1. For a and b, conduct every step of the Hypothesis testing process (1-5). a. The distribution of SAT scores is normal with u = 500, with a standard deviation o = 100. Mable believes that she scored significantly higher than average, at x = 676. Did Mable scores significantly higher than the average SAT score? b. A sample of n= 64 adults is taken from the above population and their average SAT score is measured to be M= 511. Does this sample differ from the population?
